Life's Greatest Miracle: Development of Life and Man's Biological Make-up
“Life’s Greatest Miracle” is a documentary about the development of life and how man’s biological make-up is able to reproduce itself. The discussion starts with the role of DNA in the process of reproduction. It is crucial because it holds the chromosomes that give each human unique physical trait. The combination of genes starts through the process of meiosis wherein the male and female makes sperms and eggs. The presentation then explains the inside of the male and female reproductive system and how both are different from each other. I.e. Male sperm are more on the quantity than quality while female eggs value quality. The union of the two sets of chromosome from the male and female allows a merger of new unique sets of traits. This makes up for the individuality and uniqueness of a person which is quite different from “clones.” We are not the exact replica of our parents.
The process of sexual reproduction was analyzed and discussed from an overview of the tentacles and the journey of the sperm to the vagina till it reaches the egg, and on the way the female reproductive system is set up that the process of the fertilization itself becomes a tricky business. The process is indeed fascinating because at the start the narrator tells as a matter of fact that the human body has the unquestionable urge to reproduce itself, but at the same time explains how complicated and delicate the entire process is. One ‘mistake’ from the egg and the sperm and there would be no union or meeting of egg and sperm.
The development of a fertilized egg is such wonder. Through this tiny single cell, it is powerful and capable enough to produce various organs in its own life system in just a span of nine months! The fertilized egg reproduces itself to form and multiply until each cell further develops into specific parts of the body—brain, blood, veins, foot, neck, eye, and other organs that completes the human body.
